List of differences:
Author separation with & instead of and (in text citation as well as bibliography)
First name abbr. of subsequent Authors after family name not before
Bokk title italic
Journal name italic
A blank after the colon for separating volume and pages
"In: " instead of "in" for book chapters
"pp." instead of "Pages"
also Book titles in Book chapter type in italic
Editors must be cited

Bibliography is always printed in standard OpenOffice style, can you stop this?
Journal Abbreviation is JVS

I think I mostly got it:
go here:

then download the style, using the "Raw" link on the top right.
Install by dragging the downloaded file into an open Firefox Window.
Please report back.

please don't hijack other people's threads - open a new one, so the forum remains somewhat orderly.
As a first step see here:

if that's unclear, happy to answer in more detail in your own thread ;-)
(the button is "start a new discussion" on the top right - just in case, people sometimes overlook it).

is now correct - it also has the correct name, but it won't overwrite the old style, so you'll have to manually delete that one in the styles tab of the Zotero preferences (that's just for keeping things tidy, everything will still work with both styles installed).

In Zotero 2.1, the punctuation will be ignored. There has been discussion of adding an option to compare on initials only for disambiguation (to reduce the number of gotchas over this), but that hasn't been implemented yet; the character parts of the name strings currently still need to be identical. (But Zotero 2.1 will only compare names that are actually rendered in the document, so when problems arise, they can be trouble-shot by looking at the text of the document, without digging into individual items in the database.)

Thanks for the explanation. In the case above, the difference was actually that the name was spelled out in the first reference and not in the second (when writing my previous comment I was looking at a wrong reference of Carrión). So even in version 2.1 that would result in the wrong result then.. good to know and you are right, easy to trouble-shot.

Unrelated to the issue above, but about the style: In the reference list, whenever an author has more than one initials, the first initial is followed by point+space instead of point only. So you have J. S. instead of J.S.

Should be fixed now. It was actually looking for an issue no. and if none was there it goes to DOI. I've relaxed this, so now it checks for either issue or volume and only if neither is present it assumes the article is online pre-publication and uses the DOI.
